Inspired by: https://github.com/pi-hole/pi-hole/pull/2112 A pre-start and a post-stop script are added to reduce doubled setup and cleanup code. Since systemd services do not natively support dynamic users, test once whether capabilities are supported during install/update, and remove User=pihole otherwise.
